Open source multi-platform software designed to split, merge, extract pages, mix and rotate PDF files, PDFsam Basic will cover most of your PDF related needs. PDF merge probably is the most used PDFsam module and lets you combine PDF files together. Input PDF documents can be merged completely or partially. A page selection can be easily set in the form of comma separated intervals (Ex. 1-10, 14, 25-) letting you specify what pages you want to merge for every input PDF document. The Split module let's you split PDF files at predefined or specified page numbers. The selected PDF file can be split after every page, generating a new document for every page in the original file, or after every ever or odd page. Specify the page numbers where you want to break your document. You can even tell PDFsam to split the PDF every n pages!
